209bcb9af8 netlink: specs: ovs: correct enum names in specs 
Align the enum-names of OVS with what's actually in the uAPI.
Either correct the names, or mark the enum as empty because
the values are in fact #defines.

3ada0b33c4 netlink: specs: ovs: remove fixed header fields from attrs 
Op's "attributes" list is a workaround for families with a single
attr set. We don't want to render a single huge request structure,
the same for each op since we know that most ops accept only a small
set of attributes. "Attributes" list lets us narrow down the attributes
to what op acctually pays attention to.

It doesn't make sense to put names of fixed headers in there.
They are not "attributes" and we can't really narrow down the struct
members.

Remove the fixed header fields from attrs for ovs families
in preparation for C codegen support.

643ef4a676 netlink: specs: add partial specification for openvswitch 
The openvswitch family has a fixed header, uses struct attrs and has array
values. This partial spec demonstrates these features in the YNL CLI. These
specs are sufficient to create, delete and dump datapaths and to dump vports:

$ ./tools/net/ynl/cli.py \
    --spec Documentation/netlink/specs/ovs_datapath.yaml \
    --do dp-new --json '{ "dp-ifindex": 0, "name": "demo", "upcall-pid": 0}'
None

$ ./tools/net/ynl/cli.py \
    --spec Documentation/netlink/specs/ovs_datapath.yaml \
    --dump dp-get --json '{ "dp-ifindex": 0 }'
